This patchset aims to provide a very basic version of QCOM DSP based
audio support which is available in downstream andriod kernels.
This patchset only support Digital audio based for HDMI-RX and will
add support to other features as we move on.

QDSP has both static and dynamic modules. static modules like AFE
(Audio FrontEnd), ADM (Audio Device Manager), ASM(Audio Stream Manager)
and CORE to provide this audio services.
All these services use APR (Asynchronous Packet Router) protocol
via smd/glink transport to communicate with Application processor.
More details on each module is availble in there respective patch.

This patchset is tested on DB820c, with HDMI audio playback
on top of mainline, also tested slimbus analog audio using wcd9355
with an additional small patch.

Here is block diagram to give a quick overview of the components

Changes since RFC:
- Converted APR driver to proper bus driver
- Added API version info to apr devices
- Added q6core driver.
- Fixed various issues spotted by Banajit and Kasam.
- Added kernel doc to exported symbols.
- renamed qdsp6v2 to qdsp6 as api version info can be
used from apr device.
- removed unnecessary dt bindings for apr devices.
